Hubble Space Telescope’s recent observations of FU Orionis have revealed surprising new details about the star’s accretion disk. The study found that the disk’s inner edge reaches temperatures as high as 16,000K, nearly three times hotter than the Sun’s surface. This discovery challenges existing models of stellar accretion, which had predicted lower temperatures. FU Orionis, a young eruptive star, has been observed undergoing dramatic changes since 1936, with its accretion disk touching its surface due to instability. These findings provide valuable insights into the early stages of star formation and the dynamics between young stars and their disks. The study also has significant implications for planet formation, particularly for planets forming close to the star.
